The selection of refrigerating compressorPosition:Home > Blog > Industry News

Refrigeration compressor is the main equipment, refrigeration equipment not only operating cost in cooling costs in the first place, and the investment cost in the refrigeration unit is also in charge of relatively large. Choice of refrigeration compressor is reasonable, for the efficiency of the refrigeration unit, construction cost and operation adjustment flexibility has great influence. The selection of the refrigeration compressor has the following principles:

(1), the working conditions of refrigeration's compressor, cannot exceed compressor using conditions of the factory.

(2), selection of piston compressor, when the condensing pressure and the ratio of the evaporating pressure is less than or equal to 8, should be in the form of single stage compressor; When the condensing pressure and the ratio of the evaporating pressure is greater than 8 should adopt two-stage compressor type.

(3), the selection of the compressor shall meet the requirement of refrigeration equipment production peak cooling load, load were selected according to the evaporation temperature of the machine, in order to meet the mechanical load requirements of different evaporation temperature refrigeration equipment.

(4), compressor with energy control device, adjust for stand-alone refrigerating capacity was substantial. But is only applicable to load fluctuations in the operation of the adjustment, adjustment should not be used as a seasonal load changes.

(5), the determination of single machine capacity and the Numbers should be to choose according to the principle of good for energy saving.

6, different evaporation system with compressor, alternative between each system should be considered, as far as possible the same series of compressors, swap is easy to control, management and spare parts, a series of the selected compressor refrigeration equipment should not be more than two, such as when only two machines should choose the same series.
